BAR-NARD L. OLDS, OF ST. ALBANS, VERMONT.

LINK FOR HORSE-POWERS.

SPECIFICATION forming part of Letters Patent No. 250,957, dated December13, 1881.

Application filed September 13, 1681. (No model.)

To all whom it may concern:

Be it known that I, BARNARD L. ()Lns, of

-St. Albans, Franklin county, Vermont, have invented a new and usefulImprovement in Links for HorsePowers, of which the following is aspecification.

My invention relates to the means by which thelags are secured to thejointed links of the endless treadsin horse-powers; and it consists inloops or stirrups forming part of the links and engaging slotted lags,by which arrangement 1 am enabled to use lags of uniform constructionand avoid the use of bolts.

In the accompanying drawings, Figure 1 is an inverted plan view of anumber of thelinks and the lags connected thereto. Fig. 2 is a side viewof the same; and Figs. 3 and 4 are cross-sections, respectively, onthelines 00m and 3 y of Fig. 2.

Similar letters of reference indicate correspondin g parts.

A A are the links, formed of cast-iron, and

having the wrought-iron caps a, that form loops 7 at the ends for thejoint-pins b, as usual. B B are the wooden lags, attached to the links Aby loops or stirrups c. The loops or stirrups c, by which the links andlags are connected, are preferably malleable iron, and connect rigidlyby their ends to the links. They are attached by being placed in themolds in which the links are cast. The lags are formed at their endswith crossmort-ises cl and longitudinal mortises 0, into which the loopsenter, so that the ends of the lags are firmly held, and the loops arealso covered and protected by the lag. The lags attached to the links,as shown, are held as rigidly as by bolts, and there can be no endwisemovement. To obtain the offsetting of the links required to joint them,as seen in Fig. 1, the alternate link has only to be reversed to bringits loop at the 0pposite side, as illustrated by the two positions shownin Figs. 3 and 4.. The lags need no alteration to effect this, andtherefore can be got out uniformly, instead of requiring bolt-holes indifferent positions, as is the case when bolts are used.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent 1. The horse-power link, provided with a rigid loop orstirrup, c, for connection of the wooden lag, substantially as shown anddescribed.

2. The combination of the link A, provided with loop a, and the lag B,provided with mortises that receive the loop, sfibstantially as shownand described.
